Devices are known for securing the auto.- matic advance of perforating hammers by sliding on a support under the effect of the reaction which tends to bring back the piston or striking member of the hammer, the

T; sitate the provision of teeth on the support or on the hammer. Moreover, in order to prevent the movement of advance from occurring solely in the case when the possible dis placement corresponds to a tooth of the ratchet multiple ratchet mechanism have been provided, the only eifect of which was to complicate the principle of the method of locking'itself. 1

The present invention relates to improvemcnts in the abovementioned automaticad- These improvements are vancing devices. essentially characterized by the feature that the locking is obtained by means of a wedging member carried by or guided upon a lever pivoting around a shaft of the carriage or of the hammer, the said member being automatically held wedged between the support and the carriage or the hammer by the action of a compression or tension spring acting i between the said lever and a fixed point taken on the carriage or on the hammer, the pivotal movement of the lever for dlsengageinent being obtainable only under the eifect of the reaction which produces the advance of the hammer or by hand operation.

Various forms of construction of themvention are illustrated by way of example in the accompanying drawings.

Figure 18 is an end view of the construction shown in Figure 17.

In these figures, A is a support having an I-shaped cross section on which is guided the carriage B carryingthe hammer. The support A is providedat its forward end with a beak A for fixing it in the hole a formed in the wall or. cutting face C. The carriage B in this example is provided at its front end with a cradle B on which is, carried the hammer B the contour of which is shown in dot and dash lines in Figure l. .The carriage B is guided on the upper flange A of the support beam by a C-shaped sole plate B rigid with the cradle B The cutter or drill D of the hammer may in addition be guided in a support A projecting from the front end of the support beam. The hammer may, for ease in placing it in position or withdrawing it, be mounted on the carriage B by means of a swivel Connection.

I As shown in the drawings, this swivel connection is formed by a universal jointmember comprising ashackle, or ring E engaged by a pin B projecting from the rear end of the carriage. The shackle E is provided with a part tangential to this ring havinga hole 6 for the passage of a pin E which also passes through holes formed. in the projecting arms D forming the handle of the usual hammers. The hammer is thus rendered movable round the spindle E for mounting and dismounting. It is in addition movable with the shackle E round the pin B of the car riage in a plane passing through the axis of the said spindle.

On the carriage B is mounted the wedging member F, which in this first example is carried by a lever G terminating in an operating handle. The lever pivots round a shaft 9 journalled in the carriage B. The wedging member proper F is, as clearly. shown in Figure 3, constructed in the vform of a. frame surof the hammer andcarriage with respect to ,the frame until the grip'is releasedat which is immediately rendered stationary under t rounding thesupport beam A. The transverse sides of the frame form curved surfaces f, 7, which, as shown in Figure 1, are combined in such a way as to form gripping wedges when the lever tends to be lowered by a deflection of the frame F from its vertical position. Normally the frame is held in the vertical clamping position by a compression spring H which bears at its lower end on the lever G and at its upper end on a projection formed on the head of the carriage.

' The return movement ofthe striking member of the hammer tends to advance the whole time the frame will also advance. However any recoil movement of the carrlage and frame is prevented by-the frame F being wedged on the support beam A,

Vhatever be the advance which the arrangement BD tends to make, this advance can take place freely subsequent upon each blow on the drill. Moreover, as'soon as the advance has taken place, the arrangement BD formed by the carriage and hammer, he action ofthe spring H which constantly tends to return the frame to its clamped position.

If it is desired to remove-the hammer itis lsuflicient to operate the handle of the lever G in order to raise the frame F. "The said arbodiment described above. The figures only show one part of the support beam and of thehammer carrying carriage with the assembly bolt.

In this modification, the curved combined surfaces, which secure. the wedgingof the carriage B on the support beam A, are formed by two rollers f and 7. One of these rollers fbears upon the upper flange A of the support beam. It is guided by its shaftin slots f formed in the coupled side plates of the frame F so as to be constantly retained between the flange A of the beam and the roller 'g mounted upon the pivot g of the lever Gr. 7 The other roller 7 has its axis situated in the plane passing through the axis of the roller f and through the axis of the pivot g of the lever. It bears beneath the lower flange A of the support beam in front of the point at which the roller f bears on the flange A The spring H, arranged as in the preceding example, constantly tends to keep the roller in contact with the flange A of the support beam, the axis of the roller being situated at the lower end of the slots 7. A wedging action preventing any recoil of the carriage and'of the hammer carried by the latter is thus secured on account of the clamping of the roller 7 on the flange A and of the roller f on the roller A the recoil tending to in-; crease the gripping action. Any movement of advance of the carriage will tend to make the roller f advance with respect to the roller and rotate lever G compressing the spring and releasing the grip so that the carriage and frame advances, but upon a force frame will again grip the support. r

Figures 10, 11 andlQ show in longitudinal elevation, in plan and inend' view 'respectively another constructional example of the invention. In this example the Wedging of the carriage B on the support beam A is obtained by a single member such as a roller 7 guided in the coupled plates F forming the lever F-G pivoted to the carriage. roller f bears on the one hand upon the upper-flange A of the support beam A, and on i v the otherhand on a wedging surface I carried by or formeduponthe carriage. In the example shown. this wedglng surface I.

which is arranged in such a manner thatits plane when extendedcuts the flange A of the support beam in frontof the roller f, is

' formed on a separate plate secured. by a dove-tailed joint formed'in the carriage B. The pivot of the lever FG- is formed by two trunnions g forming projections on two The plates J rigid with the. carriage B between which the support beam A is engaged. These same plates carry the spindle 7c of aguide roller K, which spindle is preferably placed vertically below the pivot of the lever. A tension spring H attached to one end of the carriage B and at the otherend to the lever FG, constantly tends to secure the-clampautomatically under the efiect of the reaction consequent upon the return of the striking member, this advance being rendered possible on account of a space between thesur face I and the roller f guided the'slots f provided, as in the preceding example, in the side plates of the lever F.

Figures 13 and'14 show a modification in which the guidance on the support is obtained'by members carried directly by the hammer, while in the preceding txamples thesemembers were carried by the carriage body. The hammer carries at tl e front a guiding slideway analogous to the slot B shown in Figure 4. At. the rear a plate carrying the wedging surface I is fixed in a member D fitted on the head of the hammer, and the hammer is guided by means of a system of two plates J assembled on this head piece, and which is entirely analogous to the guiding arrangement which, in the preceding example, was carried by the carriage. The

lever FG is pivoted'to these side plates at the wedging surface'carried by the carriage is formed by a roller I mounted on the pivot g of the lever FGr,'the wedging member 7 being formed by a roller guided in the slots f in the lever which slots are situated in plane passing through the pivot and inclined backwards with respect to the latter; A roller K carried by the plate J serves to complete the guiding of the carriage. The gripping action is normally secured by a compression spring H. r Figures 17 and 18 show in elevation and in end View respectively, a form of construe tion analogous to that shown in Figures 7 and 9 and in Figures 1 to 6. r p The wedging member in this'esample is still formed on a. frame F rigid with the op erating lever G and surrounding the support beam. This wedging is obtained onthe between the lever G and one hand between the support beam and a roller f mounted on the pivot *g of the arrangement F -G bearing on the upper flange of the sup-port beam. On the other hand a roller f formingthe lower transverse side of the frame F bears against the lower face .of the beam, this roller being pressed on the longitudinal sidesof the frame byribs f formed on the facesof the said roller, the support for the locked roller f beingobtained in front of the support for the movable roller The device comprises, as shown in the drawings an arrangementlike that shown in Figures 1 to 6 andl igures 7 to 9, in'which the compression spring l-lacts a projection on. the carriageB. v
